Solution:Balanced chemical equation:N2 + 2O2 → 2NO2According to the equation above: 2×n(N2) = n(O2) = n(NO2)Moles of each reactant:n(N2) = 5 moln(O2) = 12 molChoose one reactant and determine how many...
Solution:Balanced chemical equation:C(s) + O2(g) → CO2(g)According to stoichiometry:1 mol of C produces 1 mol of CO2Thus, 0.5 mol of C produces:(0.5 mol C) × (1 mol CO2 / 1 mol C)...
C4H10(g) + 6,5O2(g) → 4CO2(g) + 5H2O(l)n(C4H10)=m(C4H10)/M(C4H10)=56.20/58=0.969moln(O2)=m(O2)/M(O2)=85.30/32=2.666moln(C4H10)/1 and n(O2)/6.5 0.969/1 and 2.666/6.5 0.969 and 0.43The mass of water is calculated by the deficiency, by n(O2)n(O2)/n(H2O)=6.5/52.666*5=6.5*n(H2O)n(H2O)=2.05molV(H2O)=n(H2O)*Vm=2.05*22.4=45.92l=45920mlρ(H2O)=1g/mlm(H2O)=ρ*V(H2O)=1*45920=45920gAnswer - 45920g
The reaction equation:MgCO3 + 2HCl = MgCl2 + CO2 + H2OThe quantity of magnesium carbonate:2.00 g / (84.31 g/mol) = 0.0237 molThe quantity carbon dioxide is the same (according to...
